EIP-1559
Atualização da rede Ethereum de 2021 que reformulou o sistema de taxas, criando uma taxa-base queimada a cada transação e custos mais previsíveis.
Key points
- EIP-1559 was an Ethereum network upgrade, activated in 2021, that overhauled how transaction fees are charged.
- It created a base fee, calculated by the network according to demand, that is burned instead of going to whoever validates the blocks.
- The goal was to make costs more predictable and, as a side effect, to start removing part of the ether from circulation.
What is EIP-1559?
EIP-1559 is an Ethereum network improvement proposal that changed its fee system. Before it, the cost of a transaction was set by a simple auction, in which each person offered how much they were willing to pay, which made fees unpredictable and hard to estimate. The upgrade introduced a more structured mechanism for calculating that cost.
How it works
The new model splits the fee into two parts. There is a base fee, determined automatically by the network according to the level of congestion: when demand rises, the base fee rises; when it falls, the base fee decreases. In addition to it, whoever sends a transaction can include an optional tip, which serves to prioritize processing at moments of competition for space.
The most notable change lies in the destination of the base fee. Instead of being paid to whoever validates the blocks, it is burned, meaning permanently removed from circulation. The tip, on the other hand, goes to the validator. With this, the upgrade sought two effects: making fees more predictable, since the base fee is now calculated transparently, and reducing incentives for manipulation under the old auction model.
The burning of the base fee also had a significant economic effect. Since part of the ether used in every transaction ceases to exist, the upgrade began continuously removing ether from circulation, which changes the currency's supply dynamics during periods of intense use. This aspect made EIP-1559 one of the most discussed changes in the network's history, both for its practical effects on fees and for its implications on supply.
Understanding this design helps explain why network costs behave the way they do today.
Why it matters
Understanding EIP-1559 helps explain how Ethereum network fees are calculated today and why part of the ether is removed from circulation with every transaction. For those operating on the network, knowing how the base fee works provides context for costs. This is a technical concept, and it does not represent any operating recommendation.
Risks and limitations
EIP-1559 made fees more predictable, but it did not make them cheaper by itself: under high demand, the base fee can still rise substantially. The effect on ether's supply depends on the network's level of usage and varies over time. In addition, the model is specific to how the network operates and does not eliminate the need to pay for using it.
